What method of industrial boiler feed water treatment for industrial boiler feed water treatment methods are what? Treatment agent tank features are: small (1) investment, low cost, easy operation; (2) a chemical treatment combined with the outer tank, may further eliminate residual hardness; (3) environmental pollution; (4) can not be completely prevent boiler scaling; (5) water hardness inappropriate. The main method of treatment of the pot are: 1) salt method. Commonly used is trisodium phosphate, sodium carbonate (sodium carbonate), and fire (sodium hydroxide), which is the most common soda. 2) Integrated scale inhibitor law. Sodium hydroxide, trisodium phosphate, sodium carbonate and tannin extract composition Comprehensive inhibitors. Potting, there are two methods: one is administered intermittently, is continuous administration of two kinds. 3) an outer pot chemical treatment. The use of auxiliary water treatment equipment, boiler water softener recharge to ensure that qualified and softened, desalinated water.
The basic structural characteristics of water-tube boiler shell and the difference between the boiler and the boiler in the form of a shell and the difference between the characteristics of boiler water tube boilers and shell type boilers are presented in the form of double-layer structure. Referred to as outer tube boiler shell, called the inner furnace tube piece (fire tube), a circular space between the inner cylinder and the outer cylinder is filled with water, and the inner cylinder combustion chamber. When pressure medium is steam, the boiler shell is in the depressed state, the furnace is under an external pressure. Shell boilers and vertical and horizontal type. Currently used fuel in the boiler combustion gas boiler horizontal Boiler shell. Shell boilers have the following common characteristics: 1, the pot of water and stoves are installed inside the shell. 2, the metal furnace (hearth) small size, surrounded by a water-cooled, water-cooled degree of difference, a difference of combustion conditions, must be high-quality fuel combustion; 3, the heat receiving area is reduced, evaporation, or thermal power will be relatively reduced, which requires installation of water pipes or tubes pyrotechnics, and to increase the capacity of the boiler heating surface; 4, the diameter of the pot shell shell, more open, irregular shape, and unheated portions of the internal heating, the temperature and the degree of thermal expansion are different, the housing for the poor safety; water tube boiler is a boiler wherein the mixture of water, soda water or steam flowing in the pipe, and the combustion flame or flue gas flow in the outer conduit. An industrial boiler, and the heating surface of the combustion chamber which is located outside the boiler tubes, and water vapor flow through the pipe. In one aspect, the boiler water tubes in the furnace wall a plurality (water wall), having a large radiation evaporator heating surface; the other hand, the convection heating surface is evaporated is also provided outside the furnace tube bundle, the tube bundle is connected to 1 to 3. Thus, the heating area is increased, the evaporation increases greatly. The present invention also has a low consumption of metal, the structure of good elasticity, heat transfer capability, high thermal efficiency, easily improved steam parameters to achieve mechanization and automation of advantages.
